Month

A month was a unit of time measurement. According to the Fourth Doctor — who was almost certainly speaking of its duration on Earth — a month lasted 2,678,400 seconds. (TV: The Brain of Morbius) As noted by the Ninth Doctor, 12 months made up the Earth year, (TV: World War Three) which was composed of 365 days.

Months had individual names. Known months — not all of which were Earth months, and so not all of which could possibly equal 2,678,400 seconds — included:

• January
• February
• March
• April
• May
• June
• July
• August
• September
• October
• November
• December
• Clavadoe
• Hoob
• Pandoff
• Akhit
• Paztenmber
• Novrimber
• Fennestry

Behind the scenes

• Though he doesn't specify in the script of The Brain of Morbius, the Doctor's sums reflect a 31-day month.
